Hi Cno,
Well, I wouldn't say it's "better", just different. The Bryston kit was excellent and I owned it for more than 2 years. Loved it. However, I've always wanted to try the M2 since it's truly different. The bass is excellent with the Bryston gear, but the NAD is even better. Incredible detail to the bass and a very stong grip on the drivers. The NAD is equally quiet to the Bryston gear and maybe even more so. Also, the NAD doesn't change character at all as you change the volume which is something all conventional amps I've owned have been guilty of. It's a very balanced sound and pristinely clean and detailed. Plus, I consolidated my preamp, amp, power conditioner, and DAC into one single unit. Left me with money to burn as well. 🙂
